Title: A VIRTUAL KEYPAD GENERATOR WITH LEARNING CAPABILITIES
Abstract:
Methods and systems enable defining customized virtual keyboards on a touch sensitive surface, such as a touchscreen. Using learning algorithms, a computing device may learn the typing patterns of a user and "morph" the keys of a virtual keyboard into locations, sizes, and orientations that are comfortable for the user and which may reduce typing errors. A user may create a custom keypad layout by performing a series of key strokes on a touch sensitive surface. The computing device may correlate the touch locations to particular keys and generate keypad layout data that can be used to display the virtual keyboard and interpret touches on the touch sensitive surface. The computing device may monitor user typing activity and refine the keypad layout data based on detected or corrected typing errors. Keypad layout data may be exported to other devices to enable users to take their virtual keyboards with them.
